Benefits of technology

The patent is about a way to send and receive large amounts of data without interfering with other data in a communication system. This helps to improve the overall efficiency and reliability of the data transmission.

Problems solved by technology

Thus, there have not yet been proposed a specific method for allocating frequency channels to the STAs according to the data transmission / reception schemes of the STAs.
Furthermore, when interference occurs at the channels allocated to the STAs, data may not be normally transmitted / received because of the interference.

Abstract

An apparatus for allocating channels in a communication system includes: a receiving unit configured to receive terminal information from a plurality of terminals, the terminal information containing information on data transmission / reception schemes of the terminals; a checking unit configured to check the data transmission / reception schemes of the terminals and check interference at channels allocated to the terminals; and an allocating unit configured to allocate primary and secondary channels to the terminals based on the data transmission / reception schemes of the terminals, change the primary and secondary channels based on the interference, and allocate the changed channels to the terminals; and a transmitting unit configured to transmit channel allocation information on the primary and secondary channels allocated to the terminals to the terminals.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority of Korean Patent Application No. 10-2013-0039081, filed on Apr. 10, 2013, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Exemplary embodiments of the present invention relate to a communication system; and, more particularly, to an apparatus and method for dynamically allocating multiple channels to transmit / receive data between an access point (hereafter, referred to as ‘AP’) and a plurality of terminals, for example, stations (hereafter, referred to as ‘STAs’) while minimizing interference between channels to the STAs.[0004]2. Description of Related Art[0005]In a current communication system, research has been actively conducted to provide various qualities of services (hereafter, referred to as ‘QoS’) having a high transmission rate to users. Examples of the communication system may include a wireless local area network (h...
